Lip injections/botox?!

This is something I could talk to my friends about but I really want a non biased opinion from you ladies out there that don’t know me or my partner. OK so my and my BF have been together for 4 years, we took a small 6 month break last year and I ended up getting lip filler (he would never allow me to get it while we were together) and when we got back together he promised me that he wouldn’t make a big deal about it, that if I wanted to get filler every 6 months to maintain my lips - it was ok with him. So that was GREAT, lips were a huge insecurity of mine and it really made me happy that we were on the same page. Fast forward to 10 months later, he now wants me to stop getting lip filler AND does not want me to start getting Botox (something else I’m interested in getting) until after we’re done having kids. This could be 5-7 years down the road?!? I completely agree with not getting these procedures done WHILE pregnant or WHILE breast feeding but i don’t see the problem with getting it done in between. His reasoning is because these substances stay in your body for months after injections and he thinks it can cause harm to a baby while pregnant. He’s controlling in other areas of our relationship too so I think this is more of a control thing than a « safety » thing. Girls..what are your thoughts on getting these procedures done in between pregnancies? Is it wrong of him to request this or am I over reacting?
